Answer:
7
Step-by-step explanation:
Note the values on the right are 7 times the corresponding value on the left side, that is
15 × 7 = 105
12 × 7 = 84
4 × 7 = 28
Then
1 × 7 = 7 ← required value
Step-by-step explanation:
5(2x+4)=15
10x+20=15
10x=15-20
<u>1</u><u>0</u><u>x</u>= <u>-</u><u>5</u>
10. 10
x=-1/2
For this case we have the following equation:
To solve we follow the steps below:
We subtract 24 from both sides of the equation:
We divide between -3 on both sides of the equation:
The value of x is 17
